IV'ITJV'ESSIL'S PATENT JABEZ T. WARREN, OF LE ROY, NEW YORK.-

HORSE-POWER.

SPECIFICATION formingpart of Letters Patent No. 240,480, dated April 19, 1881. Application filed March 22, 1881. (No model.)

To all whom it may concern:

Be it known that I, JABEZ T. WARREN, of Le Boy, in the county of Genesee and State of New York, have invented certain new and useful Improvements in Horse Powers, of which the following is a specification.

In Letters Patent No. 228,576, granted to me June 8, 1880, a horse-power is shown similar in general construction to that herein described; and my present invention consists in certain improvements on that class of machines, as will hereinafter be set forth.

In the accompanying; drawings, Figure l is a perspective view of my improved machine; Fig. 2, a sectional view on the line 2 2 of Fig. 3; Fig. 3, a vertical section onthe line 3 3 of Fig. 2; Fig. 4, a detached view, partly in section, showing the manner of driving the planet-wheels and of attaching the sweep to the top plate of the machine; and Figs. 5 and 6 are detail views of the knuckle or tumbling rod connection.

The casing of the horse-power, which consists of a drum or barrel, A, and two end plates, a to, securely united by bolts B, is fastened to a frame or bed-plate, X. A vertical shaft, 0, turning in hearings in the plates at a, carries a large bevel-wheel, D, within the drum and a pinion, E, near its upper end, above the plate a. The bevel D gears with a bevel-pinion, cl, upon the power-transmitting shaft H, which has its hearings in the casing. The shaft 0 is driven by the planet-wheels F F, which gear with the pinion E and the internally-geared ring G, which, in this instance, is shown as made in one piece with the plate a. The top plate, I, to which the sweep K is attached, turns upon the shaft 0.

Thus far the construction of the machine is the same as that shown and described in my patent above mentioned. In that pat'ent,however, the planet-wheels are shown as driven by a round pin or lug on the top plate, which enters a corresponding socket in the wheel. In the present case the wheels are provided with a central hub or trunnion, f, having an annular depression or recess, f, around it. The trunnion f has its bearing between two lugs, i 'i, on the top plate, the outer sides of which are curved to conform to the recess f, and their bearing-faces next the trunnion straight, to present a small surface of contact. By this construction the machine can be run equally well in either direction, friction and wear are very much reduced, and constant oil-- Two planet-wheels are shown, but obviously a single wheel may be used, or more than two. I attach the sweep K to the top plate, I, so that it can be adjusted in height to suit horses of different sizes, and in length to suit the floor or space in which the machine is working. A lug, 0, having an eye therein, is formed upon the top plate, to one side of the shaft 0. Directly in front and rear of this lug are rests or socketsM M, of differenthei ghts, for the sweep, which rests are cast or otherwise formed on the top plate. Two such lugs and pairs of. rests are shown for the attachment of two sweeps to the machine. The sweep is secured in place by a right-angle bolt, 70, and nut the bent end of the bolt entering the eye in the lug c and its long arm passing through the sweep. The bottoms of the rests are beveled in the same plane, so as to give to the sweep a firm support. The sweep is adjusted in height by interposin g a plate or plates, N,between it and the reststhe higher or the lower one, accordin g as it is desired to elevate or depress its outer end to suit the height of the horse. Boltholes W, of which there may be any suitable number, are made in the sweep, so that it can be adjusted in length for the purpose above mentioned. The draft devices are similar in principle to those shown in my patent before mentioned, where the horse faces the sweep, the whiffle or sweep and are pivoted to the evener Q, which is pivoted to the draft-hook q. By this construction I attain great cheapness, simplicity, and durability. The power is transmitted from the shaft H to the tumbling-rod R by a flexing knuckle or joint, S. This joint consists of a socket, s, in the socket-openin g s of which the head 7', which fits loosely on the squared end of the tumbling-rod It, works. The portion 8 of the socket s fits loosely on the squared end of the shaft H, so as to revolve with it. The parts are prevented from separating by a collar, T, at the outer bearing, T, of the tumblin grod. The head 1' is square in transverse sec tion, as shown in Fig. 6, and is rounded in longitudinal section, as shown in Fig. 3. The socket-opening s is square in cross-section to fit the head 1", and its inner end is curved to correspond with the curve of the head. The head and its socket, instead of being square in cross-section, may be of any other angular shape. By this construction the tumbling-rod is free to flex, and can be driven at any desired angle within certain limits. The joint is very efficient, can be cheaply made, and readily put together. I also dispense with the danger as well as the expense and trouble incident to joints where knuckle-pins are used.

The improvements above described are, of course, applicable to many machines differing somewhat in construction from that herein shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the planet-wheel, having the trunnion and annular recess, as setforth,.

of the top plate, and the lug or lugs which form the bearing of the trunnion, substantially as described.

2. The combination of the top plate, the sweep, rests or sockets for the sweep, mechanism for securing the sweep in place, and removable plates for regulating the height of the sweep, substantially as described.

3. The combination of the top plate, the lug and bolt for securing the sweep to the plate, a rest or socket on each side of the lug, the rests being of different heights, and removable plates for regulating the height of the sweep, substantially as described.

4. The combination of the sweep having a series of bolt-holes therein, the top plate, rests for the sweep, and a bolt for securing the sweep in place, whereby the sweep can be adjusted in length, substantially as and for the purpose set forth.

5. The combination of the sweep, the shafts attached thereto, the pins on the shafts, the slotted draft-rods which rest and slide on the shafts, and the evener, substantially as described.

6. The combination of the shafts H and R with the knuckle or flexing joint, herein described, for transmitting power, consisting of a head which is angular or square in cross-section and rounded in longitudinal section, and a socket angular or square in cross-section, in which the head works, substantially as set forth.

7. The combination, substantially as described, of the shafts H and R, the socket 8, having the socket-opening s, and the head 1".

In testimony whereof I have hereunto subscribed my name.
